Localization studies under triaxial conditions
Acoustic emissions and conventional strain measurements were used to follow the evolution of the damage surface and plastic potential in a limestone under triaxial compression. Confining pressures were chosen such that macroscopically, the limestone exhibited both brittle and ductile behavior. The parameters derived are useful for modeling the deformation of a pressure-dependent material and for computing when localization would occur. For modeling, simple approximations are adequate, but a more complete understanding of the evolution of the various parameters is necessary in order to calculate when localization can be expected. 11 refs., 6 figs.
